You know who is feeling up to discussing her personal life? Emma Watson, who tells Vogue U.K. that last year she went through a "horrendous" with ex-boyfriend Matt Janney. How horrendous are we talking? It involved a vow of silence. No, seriously. "I felt really uncomfortable," Watson says. "Even before my relationship ended, I went on a silent retreat because I really wanted to figure out how to be at home with myself."
